well firstly i am a tree grower and bbhp is not a strain that stretches or like to branch. Which for me does not make it a great candidate for tree growers. I have run it twice now and i will get maybe a 1/3 of the weight that i would expect from a good yielder. I had it alongside silver mountain on the first run, popped the seeds at the same time and the Sm keeper yielded 3 times more than the bbhp keeper. My amnesia yielded nearly the same too but wasn't from seed.
However if i had run a number of smaller plants i think the yield would be good. It has some great qualities - 8 week finish, dense, frosty, great terps - i am not criticising that strain but it doesn't really suit my style of growing.
